i dont know what to do anymore

im 14 and hopless. i really dont know what to do anymore with my life, ive never felt so defeated in my entire life. i really need someones help but i dont want to bother or annoy anyone. i have been sh for a while now and i cant stop. i really dont want anyone to find out, but deep inside i want someone to notice so that they can know how much im struggling. i want to tell my teacher, but i dont know if i can trust that she wont tell my parents, cause i know ill get into so much trouble if my parents find out. ive really reached the end of everything. i dont even know why im still here and i lowkey just make so many peoples lifes worse. i cant do this anymore i really cant.
